Product description: A switch series in three design versions, several colours and a choice of surface materials. Function description: Light switches, seamless integration into intelligent building systems. Design aspects: Developed in consultation with actual users architects, contractors and end users. Three separate design lines mean lots of creative space for e.g. planners: kallysto.pur in clear form; kallysto.stil in softly curved harmonious form; and kallysto.art in a reduced timeless elegance, with panorama switch plates and shadow effects to give a floating appearance. Any front plate or rocker switch can be combined with any another.
